MOTOR-WHEEL FOR CYCLES- Specification of Letters Patent.

Patented Nov. 24, 1908.

Application filed April 1, 1907. Serial No. 365,654.

To all whom it may concern:

Be it known that I, JULES EMILE Flinn.- LARD, a citizen of Switzerland, residing at Geneva, Switzerland, have invented certain new and useful Improvements in Motor- Wheels for Cycles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to fi res of reference marked thereon, which orm a part of this specification.

The objects of the present invention are to construct a motor-wheel which is very flat so that it can be placed in a common bicycle frame, to provide means whereby the motor can be disconnected and the road-wheel turned by the pedals of the cycle, and to secure other advantages and results as ,will.

be hereinafter described and finally pointed out in the claims.

I am aware that several attempts have been made to construct road wheels for cycles carrying upon a fixed spindle a motor located inside the wheel to drive same, but none of the constructions known to me have been successful and'in public use.

In the accompanying drawings, like letters of reference indicate similar parts in all the figures where they occur.

Figure 1 is a vertical section through the road-wheel showing in elevation the motor located therein; Fi 2 is a part side eleva-. tion of the wheel a ter removal of a central disk giving access to the motor, and Fig. 3

illustrates a detail of the mechanism which serves to operate a friction clutch adapted between the road-wheel and the motor.

Inthe said drawings, M is the explosion motor which is suspended upon the spindle A made in two arts encircling the motor with their inner orked ends united by 'bolts 11-. The spindle A is firmly slipported in the hind fork b of the bicycle rame' and the road-wheel is made out of two parts, a drum 0 carrying the pneumatic tire and'a disk 0 bolted upon the said drum. The road wheel thus has a divided hub which is adjusted upon the spindle A to each side of the motor through intermediary of ball bearings f. The motor M is especially fiat and carries all its accessories, carbureter, exhaust, igniter, a. s. o. It receives fuel by a pipe passing through the bored out left hand part withdraw the stem n.

which engages a toothed wheel It i e upon the right hand part of the spindle A.- This ear wheel meshing with the motor inion orms one half of a friction clutch w ereby the road-wheel is carried around the motor and fixed spindle A, the other half of said clutch being secured to the road-wheel. This latter part consists in a spring-actuated disk 71 with a peripheral conical crown 2" covered with leather, fiber or other ap ropriate material capable to gri smoot ly upon the corresponding conica contact surface near the periphery of the gear wheel h.

The clutch part i is carried by fingers 1 upon the wheel disk 0', it is adapted to slide upon said fingers and constantly pressed against the ear wheel h by springs Z mounted upon said fingers Z between the wheel disk 0 and the clutch part '5. This latter has a hub p mounted idly upon the spindle A and is ada ted to slide longitudinally upon the said spindle so that it may serve to uncouple the clutch if one withdraws the part i from the gear wheel h. To effect this separation a clutch operating mechanism serves which consists in a stem n located in the bored out right hand side spindle part A and a cam cap 0 mounted upon the outer end of said stem. This cap 0 meshes with a cam disk 9- having tooth shaped cams g (Figs. 1 and 3) so that by turning the cap 0 a given angle it will mount upon said cams and This latter has a transverse pin m which engages the bearing p of the clutch disk 2' so that when the stem n is drawn out, the said disk 2' is removed from the gear wheel it against the resiliency of the springs Z and the clutch, uncoupled whereby the motor and road-wheel become disconnected. The cam cap 0 has a lever 0 whereby it can be turned and which is connected by a chain or wire to a hand lever upon the guidon (not shown in the drawing) to operate it. This hand lever can even be combined with a locking device to keep the motor permanently disconnected from the road-wheel. Upon the latter is secured a pinion 7 which permits to drive it by chain from the pedals to start the motor and to run the wheel without the motor. In Fig. 1

described and invention and be performed,

comprising a mounted on a a being secured vrting a motor a fixed spindle a gear-wheel meshing with ounted on the )n the second nd adapted to ntact with the a stem in the 1 connected on iperate it, and )f the stem for comprising a a motor theret vehicle frame he spindle beclutch member secured to the hereon, a stem ndle and con- Iv- Vila am the for mg, 75 1th to operate it against the springs, and means on the projectlng end of the stem for its manual manipulation.

4. A motor driven wheel comprising a hollow drum forming a wheel, a motor therein, a fixed spindle secured in a vehicle frame and supporting the motor, the spindle being perforated on one end, a clutch member on the motor, a clutch member on the wheel and having springs to normally throw it in engagement with the clutch member on the motor, a stem in the spindle having a pin transversely arranged on its inner end to engage the sliding clutch member to operate itagainst the action of the springs, and means on the projecting end of the stem for its manual manipulation.

5. A motor driven wheel comprising a hollow drum forming a wheel, a motor therein, a fixed spindle secured in a vehicle frame and supporting the motor, the spindle being perforated on one end, a clutch member on the motor, a clutch member on the wheel and having springs to normally throw it in engagement with the clutch member on the motor, a stem in the spindle having a pin transversely arranged on its inner end to engage the sliding clutch member to opmember, and means on the end of the stem for operating it.

A motor driven whee drum and a disk thereon both fixed spindle, the fixed spindle in a vehicle frame and suppc mounted inside the wheel, tilt '10 being perforated on one end on the motor, a gear-wheel the first gear and loosely m spindle, a friction surface gear, a clutch on the wheel a 15 be thrown into and out of co friction surface of the gear, perforation of the spindle am one end with the clutch to c means on the projecting end 20 operating it. r 2. A motor driven wheel 1 hollow drum forming a wheel in, a fixed spindle secured in a and supporting the motor, t: 25 ing perforated on one end, a i onthe motor, a clutch member wheel and arranged to slide t in the perforation of the spi Cram: .w a5diiIS'U" bu6a\fi/I\ n \71' m le 51 31111 a cam cap on the projecting end of the st cams on the vehicle frame for engaging cam cap, and means on the cam cap turning it.
